GreenWhey Energy converts waste water into electricity

Every day at cheese factories in northwestern Wisconsin, tanker trucks haul away thousands of gallons of waste-water. Much of it is taken to nearby farms, where it is sprayed across the fields as fertilizer.

The waste is high in nutrients like phosphorus and nitrogen. If it runs off the fields into nearby lakes and rivers, it can cause unhealthy amounts of algae in the water.

GreenWhey Energy, a new company in Turtle Lake, is now taking some of that waste, removing much of the harmful material, and using it to generate electricity.
